- ROLLER-BEARING.

Y Specification of Letters Patent.

Patented May i2, 1914.

To all whom it may concern Be it known that I, DELEVANTE W. Caos LAND, asubject of the' Kingof. England, re-

siding at Newark, in the county of Alameda and State of California, haveinvented certain new vand usefulI Improvements in RollerfBearinga ofwhich the following is a specification, reference being had to theaccompanying drawings.

This -invention v,relates to new and useful .improvements in rollerbearings for wheels simple and urable in construction, being inexpensiveto manufacture and at the same timevery eiiicient and useful inoperation.

With these and otherV objects in view, this invention consists in thenovel combination and arrangement of parts whereby all the rollers arec'aused to maintain each other in their relative positions by cohesion,as will be hereinafter particularly pointed out.

vthe exterior of which can be any desired shape. The interior isprovided with a re cess 2 around its inner periphery in which are seatedseveral parallel main rollers 3. These main rollers .are equal in lengthto the width of the recess 2 so that there will be no axial movement ofsaid main rollers 3 in the bushing l and in order to space these mainrollers 3 equally from one another, I provide idle rollers 4. These idlerollers are smaller in diameter and of greater length than the mainrollers 3 and have their ends which project equally beyond the ends ofthe main rollers, grooved, Vas shown at 5. These idle rollers 4 whichactually Contact hoops encircling and contacting with they outerperipheries of said projecting ends 5,

but the outer peripheries of these langes'or hoops do not contact withthe inner periphery -of the'bushing. l. In order to retain saidprojecting ends within these hoops or the like, I provide a pair offreely rotating rings 6 which are disposed within the grooves of theprojecting ends of said idle rollers 4.

v A horizont-al journal or the like 10 which is disposed through the.bushing l, contacts with the inner peripheries of Vthe main rollers 3and forms a track for the latter t0 roll upon. This journal lO can befitted to any axle or shaft l2 and secured thereon. I also provide apair of collars 1l which are removably secured on said journal l0 toretain the rotating covers 7 in position and thus keep the parts of theroller bearing together. It will, therefore, be seen that the idlerollers, contacting with the main rollers, will revolve in thereversedirection to the latter; also that the rotating rings 6,contacting with the inner circle of the projecting ends of the idlerollers will rotate in the same direction as the bushing 1, while therotating covers 7 will rotate'in the same direction as'the shaft or axleand the rotating -ring 6 will, ofcourse, rotate in the reversedirection.

From the foregoing it will be seen that I have provided a simple,inexpensive and efficient means for carrying out the objects of theinvent-ion and while I have particularly described the elements bestadapted to 'perform the functions set forth, it is obvious that variouschanges in form, proportion and in the minor details of construction maybe resorted .to without departing from the spirit or sacrificing any ofthe principles of the invention.

Having thus described my device in detail, what I particularly claim asmyinvention is In a roller bearing, acasing provided with `an annularrecess in its inner face, a journal adapted to accommodate a shaftextending lOOv I the load bearing rollers and provided with annulargrooves, closing covers for the ends ofthe casing surrounding thejournal and capable of independent movement therearoun'd, each of suchrings being provided with a flange directed inwardly of the casing andaffording a bearing surface tocontact -with the pro] ecting ends of theintermediate rollers, means for `holding the closing coversagainst'endwise movement on the Journal,

and freely rotatable rings surrounding the vjournal and interposedbetween the latter and the ends of the intermediate rollers andaccommodated within the grooves Aof said -last named rollers.

In testimony whereof I hereuntoax my signature in the presence of twowitnesses. DELEVANTE W. CROSLAND.
